 Â Â Â  * include/bits/stl_deque.h
 Â Â Â  (fill, copy, copy_backward, move, move_backward): Move overloads for
 Â Â Â  std::deque iterators directly in std namespace.
 Â Â Â  * include/bits/deque.tcc: Likewise.
 Â Â Â  * include/debug/deque (fill, copy, copy_backward, move, move_backward):
 Â Â Â  New overloads for std::__debug::deque iterators. Forward to normal and
 Â Â Â  optimized implementations after proper debug checks.
 Â Â Â  * testsuite/23_containers/deque/copy.cc: New.
 Â Â Â  * testsuite/23_containers/deque/copy_backward.cc: New.
 Â Â Â  * testsuite/23_containers/deque/fill.cc: New.
 Â Â Â  * testsuite/23_containers/deque/move.cc: New.
 Â Â Â  * testsuite/23_containers/deque/move_backward.cc: New.
